sorry but my first post is a complain. I have bought a Kindle and am very satisfied with it; I am using it since several months and have bought many books on the Web, reading them without any problem. With the pdf books it's all very easy, I can translate them in txt and then transfer them to my Kindle. With the introduction of this proprietary ACSM, the text is in Flash and although I can highlight it, I am forbidden to copy it in a txt window. So the problem is not Amazon and Kindle: it is Adobe's format and their use of a format that forbids copying.

Though I understand the problems with piracy (of a book? uhmm....) this is not something that I am ready accept when I have correctly paid my money for a e-book that I want to read on whatever e-reader I have decided to purchase.

I hope that Adobe will reconsider this. Meanwhile I had to ask for a refund of my e-books in ACSM and I am thinking of canceling my Adobe account as it is useless for what I would need it.

I have to agree with Stefano. I just bought a book that I am unable to read because the seller told me to use Digital Editions without informing me that Digital Editions can't be used by Kindle. I feel cheated. Kindle is used by so many and I'm surprised there isn't a clear warning when you download Digital Editions that it isn't compatible with Kindle. Even on this website, I had to search the forums for this information. It might be somewhere else, but I could not find it. I had to read this information on the Calibre website but then I had already bought the book. The only reason I got the Adobe account was because of my e-reader so this account is also of no use to me.

Your expectations don't match reality. If you are buying a book from somplace other than Amazon, unless they specifically say that they support Kindle (or sell the content in non-DRM Mobipocket format), then they don't support the Kindle. Amazon would prefer if you could only buy content from them.

This is Amazon's fault (they could have - and still could - add in support for the Industry Standard - EPUB - but consistently choose not to, and even gone so far to withdraw from the standard body - IDPF, which shows their complete lack of interest).

I disagree with buying from amazon only for the kindle, amazon doesnt't have the harry potter books only pottermore and I know that they can be transfered to the kindle with no problems, I just bought a book from waterstones and was told to download ADE to read it, not knowing about it but my local store said it should be able to transfer to a kindle with no problems as I'm grabbing most of my books in time for xmas as that is when I'll be getting my kindle keyboard.
